sccs-comb

sccs-comb(1)							   User Commands						      sccs-comb(1)

NAME

       sccs-comb, comb - combine SCCS deltas

SYNOPSIS

       comb [-os] [-csid-list] [-psid] s.filename...

DESCRIPTION

       comb  generates	a  shell  script (see sh(1)) that you can use to reconstruct the indicated s.files. This script is written to the standard
       output.

       If a directory name is used in place of the s.filename argument, the comb command applies to all  s.files  in  that  directory.	Unreadable
       s.files	produce  an  error; processing continues with the next file (if any). The use of `-' as the s.filename argument indicates that the
       names of files are to be read from the standard input, one s.file per line.

       If no options are specified, comb preserves only the most recent (leaf) delta in a branch, and the minimal number of  ancestors	needed	to
       preserve the history.

OPTIONS

       The following options are supported:

       -o	     For  each	`get -e' generated, access the reconstructed file at the release of the delta to be created. Otherwise, the recon-
		     structed file is accessed at the most recent ancestor. The use of -o can decrease the size of the	reconstructed  s.file.	It
		     can also alter the shape of the delta tree of the original file.

       -s	     Generate  scripts to gather statistics, rather than combining deltas. When run, the shell scripts report: the file name, size
		     (in blocks) after combining, original size (also in blocks), and the percentage size change, computed by the formula:

		     100 * ( original - combined ) / original

		     This option can be used to calculate the space that is saved, before actually doing the combining.

       -csid-list    Include the indicated list of deltas.  All other deltas are omitted. sid-list is a comma-separated list  of  SCCS	delta  IDs
		     (SIDs). To specify a range of deltas, use a `-' separator instead of a comma, between two SIDs in the list.

       -pSID	     The SID of the oldest delta to be preserved.

ATTRIBUTES

       file(4), attributes(5)

DIAGNOSTICS

       Use the SCCS help command for explanations (see sccs-help(1)).

BUGS

       comb might rearrange the shape of the tree of deltas. It might not save any space; in fact, it is possible for the  reconstructed  file	to
       actually be larger than the original.
